向量和

On the whole, we do as follows: Firstly, we list some conceptions and lemmas for later use. Secondly, we inducted the absolute value norm in the two-dimensional vector interspace, and also proved the two-dimensional vector interspace is a Banach Interspace. Thirdly, we define two-dimensional vector-valued functions on a interval by the definition of -fine partitions in part 1. Then, some sufficient and necessary conditions of integrabel are given, and discuss the property of the integral on two-dimensional vector-valued functions.

主要包括以下内容：在第一部分，我们介绍了本文所用到的几个基本概念和引理；第二部分，我们在二维向量空间中引入了绝对值范数，并且证明了二维向量空间是一个Banach空间；在第三部分中，通过第一部分关于-精细分划的定义，我们给出了在某区间上二维向量值函数积分的定义以及可积的充分必要条件，并讨论了二维向量值函数积分的一些性质。

Some nonexistence results for p-degenerate sub-elliptic first order evolution inequalities associated with the generalized Baouendi-Grushin vector fields are given. The method is an improvement of the admissible function method in Euclidean space. The proof hardly depends on the properties of the generalized Baouendi-Grushin vector fields.

通过改进欧氏的容许函数法，应用广义Baouendi-Grushin向量场的一些性质，选取特殊的容许函数，利用Hlder不等式和Young不等式，证明了由广义Baouendi-Grushin向量场构成的p-退化次椭圆一阶发展不等方程，在适当条件下非平凡弱解的不存在性。

Linear algebra also plays an important part in analysis, notably, in the description of higher order derivatives in vector analysis and the study of tensor products and alternating maps.

这样向量可以用来表示物理量比如比力，可以做加法或和标量做乘法。如此形成了第一个例子：实数向量空间。

教材从空间向量与坐标入手，主要以向量为工具，研究空间中的一些几何图形及性质，不论从知识上还是从思维上，都是对中学内容的加深和提高。

First,the distance ratio between within-class and between-class of each column of mixing matrix is computed by using a distance measurement.Then,for each class,the mixing matrix and independent components are re aligned by sort ascending according to the distance rate,and the columns of the weight matrix with smaller distance ratio and the corresponding features are reserved.Finally,the best feature set is selected by genetic algorithm from these foregoing feature vectors.

首先，使用一种距离度量来计算混合矩阵每一类的类内类间距离比；然后对每一类按该比值由小到大重新排列混合矩阵和独立分量，保留权重矩阵中类间类内距离比大的列，及其对应的特征向量；最后对这些特征向量使用遗传算法选择最优特征组。

However, Grassmanns system is so abstract and far away from the tradition as not to be understood. Its influence on the foundation of modern vector analysis is not as it should have impacted although it does affect on the axiomatization of vector theory.

遗憾的是，由于格拉斯曼的系统内容过于抽象和偏离传统而难为时人理解，它对现代向量理论的创立没有起到应有的作用，但格拉斯曼的工作却对向量的公理化具有较大影响。

It is worth generalizing and to be studied.

用本文提出的新方法研究了大庆油田某油藏的油气水层识别问题，结果表明最小二乘支持向量机的油气水层识别方法较人工神经网络和标准支持向量机的油气水层识别方法具有更快的运算速度和准确率，是一种值得进一步研究及推广使用的方法。

Prediction approach of potentiality for environmental factors pH,temperature and dissolution oxygen on yeast fermentation was proponed,Based on constructing the membership functions of environmental factors on fermentation process,the fuzzy relation equation model was formed from fuzzy evaluation vector,membership grade matrix and factor weight vector.

提出一种预测环境因子pH、温度和溶氧对酵母发酵影响潜力的方法。在构造环境因子对发酵过程评价的隶属函数的基础上，建立由模糊评价向量、隶属度矩阵和因子权重向量构成的模糊关系方程模型。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
